Installing the Process Protection
RTD Sensor
(HTC Only)
The process protection RTD probe is a safety sensor that prevents the HTC’s heater
from overheating in case of a process temperature sensor failure or insulated hose
failure.
The process protection RTD sensor senses the temperature leaving the heater
assembly to prevent damage to the process or the product within the CH Hopper. It
generates an alarm on the HTC control panel (A-49 or A-50) and shuts the heater
off if the air temperature exceeds the process protection setpoint. The element for
this sensor is to be mounted in the heater assembly outlet nozzle before the insulat-
ed hose is connected.
1
Insert the process protection RTD probe into the heater assembly outlet
nozzle.
Center the end of the probe in the outlet so that the tip does not touch
the inlet tube walls.
2
Tighten compression fitting of the
probe to lock the RTD in place.
3
Route the process protection RTD
cable towards the location of the
HTC control panel.
